FLUE-STOPPER.

SPEOFICATION forming part of Letters Patent N o. 622,221, dated April 4,1899. Application filed April 2,1898. Serial No. 676,158. (N0 model.)

To @ZZ whom it may concern:

Be it known that I, I-IILAND GOODWIN, of Vauseon, county of Fulton,andState of Ohio, have invented certain new and useful Improvements inFine-Stoppers; and Ido hereby declare that the following is a full,clear, and

eXact description of the invention, which will.

enable others skilled in the art to which it ap'- pertains to make anduse the same, reference being had to the accompanying drawings, and tothe figures of reference marked thereon, which form part of thisspecification.

My invention relates to an adjustable fluestopper of that characteremployed in closing the opening in chimneys when the pipe is withdrawn.

The object of the invention is to provide an inexpensive closure withmeans for securing the same frictionally within a due-opening,comprising a fore-plate, an inner plate independent, straps marginallyconnecting the same, a stirrup carried by the inner-plate, and athreaded bolt carried by the outer plate, said bolt screwing into anorifice in the stirrup, whereby when the bolt is revolved the plates arebrought together and the stopsV are flexed outwardly against the Wall ofthe flue.

In the drawings, Figure lis an elevation of the stopper as seen lookingfrom the rear side, it'being understood that the front plate may be ofany desired face ornamentation. Fig. 2 isa longitudinal central sectionof the stopper shown as inserted within the iiueopening of the chimney,the .chimney being' in horizontal section.

The usual flue-stopper vcomprises a faceplate and spring-arms to impingeagainst the wail of the opening to the iiue. I have discovered that aconsiderable proportion of fires is due to the fact that under excessivepressure, due to expansion of the atmosphere in the fluewhen incondition of receiving more than ordinary heat, the flue-stopper isforced out of place, either partially or entirely, thereby allowing theheat, and in many instances the flame, to escape through the flue-opening, and in often causingafire. Itis true it may result in frequentcharring before the inal blaze; but the result is inevitable. I haveavoided this possibility by, rst, providing for so frictionally securingthe face-plate that displacement is impossible, and, second, inproviding a supplemental plate that shall be in close alinement with theinner wall of the flue and so nearly its diameter that the heat andflame are caused to pass the opening and ascend the chimney.

l designates the chimney; 2, the opening, usually provided with athimble 3. The faceplate 4 is of the usual or any preferred face orornamentation, and to the inner side and marginally thereof is secured aplurality of metal straps 5. I prefer to employ four of these straps,although a greater or less numa ber may be employed, if desired. Theopposite ends of the straps 5 are secured near the margin of the plateor disk 6 of very nearly the diameter of the flue-opening 2, and thestraps 5 are of a length to cause the face-plate 4 and plate 6 to beseparated practically the distance of the thickness of the chimney-wall,so that when the stopper is inserted the disk 6 will coincide, or nearlyso, with the inner face of the chimney-wall, and thereby prevent \anytendency to drafts throughthe opening.

To the plate 6 there is secured a stirrup 7 which projects outwardlytoward the faceplate and receives a nut 8, the stirrup being reduced tohold the nut from revolution, and projecting through an orifice 9centrally of the `face-plate is a threaded rod l0, having a knob l1 uponits outer end. `Witl1 this conastruction, the stopper being insertedwithin the opening 2, the knob 1l and also threaded rod l0, is revolvedto run the threaded rod into the nut 8 to ileX the straps 5, so thatthey will bear with any desired amount of friction centrally of theirlengths against the wall of the opening 2, as clearly shown in Fig. 2.It will be seen that by this provision there is full compensation madefor openings of varying diameters, and that the stopper may be securedwith any desired frictional resistance.

A Hue-stop, comprising the thimble, a faceplate having ribs leading froma central aperture therein, combined with a disk 6 and flexible strapsconnecting the latter with the inner face of said plate, a yoke bentnear its middle, forming two right angles, thence each arm ofthe yokeoutwardly inclined and having their angled ends secured to the disk 6, a

threaded rod with knob thereon, said rod dismy own I hereby affix mysignature in presnosed in registering :tpertu res in the yoke and enceof two Witnesses. face-plate, and a nut on Jthe threaded end of Y T l fthe rod, said nut being prevented from rota- HILABD GOODWIN 5 tion bythe parallel portions of the yoke, ns fitnessesz shown and described.NILLIAM YVEBSTER, In testimony that I Claim the foregoing as .IEANETTAIIISLOP.
